EmEditor 10.0.6 on Windows 7 (32-bit).
Start EmEditor with a blank document. Click Macros -> Customize. (List of macros is empty). Click OK.
Result: EmEditor crashes.
(Screenshot from Polish version of Windows 7. Exception code is c000005, which I guess is “access denied”)
Same as above, trying to add a macro to the list in the Customize dialog. I can add a macro file to the list, but clicking OK causes the same crash. Likewise, pretty much anything I try to do under the Macros menu (such as the Edit command) causes the same crash.
This must be a fairly recent problem, because I have used macros a lot in EmEditor before and never encountered this.
